IPsec VPN provides secure encrypted communication over IP networks, commonly used for secure tunnels over the internet. It operates in transport or tunnel mode and uses components like…
A Virtual Private Network (VPN) creates a secure, encrypted connection over the internet, allowing remote access to corporate resources. It works through encryption protocols, VPN clients, servers, and…
The Virtual Router Redundancy Protocol (VRRP) increases router availability by forming a backup group of routers sharing a virtual IP. It elects a master router based on priority…
Gateway Load Balancing Protocol (GLBP) is a Cisco protocol for automatic gateway redundancy and load balancing. Unlike HSRP or VRRP, GLBP allows multiple active gateways, distributing traffic load…
Hot Standby Router Protocol (HSRP) is a Cisco redundancy protocol for ensuring a fault-tolerant default gateway in a LAN. It creates a virtual router shared by multiple physical…
Gateway redundancy is a crucial network configuration providing backup gateways if the primary one fails, ensuring continuous internet or network service. Protocols like HSRP, VRRP, and GLBP enable…
A MAC table, or CAM table, is crucial for network switches to route Ethernet frames efficiently based on their destination MAC addresses. It maps MAC addresses to switch…
Dynamic routing allows routers to automatically calculate the best path between nodes and update their routing tables. It features automatic updates, scalability, and adaptability. Common protocols include RIP,…
Static routing involves manually configuring routes in a router's table, providing simplicity and control but lacking automatic adjustments seen in dynamic routing. It requires no routing information exchange…
Routing protocols play a crucial role in network operations by enabling efficient data transmission. They include Interior Gateway Protocols (IGP) like RIP, OSPF, and EIGRP, and Exterior Gateway…
